Explanation:

• Question 4: Endurance training, like running or cycling, elevates heart rate and breathing, enhancing cardiovascular and respiratory efficiency. Strength training builds muscle, flexibility training improves range - of - motion, and agility training focuses on quick movements.
• Question 5: A certified fitness professional has the training and credentials to safely and effectively lead group fitness classes. A sports science student may lack practical leading experience, a gym member with experience might not have formal training, and a health and wellness coach's scope is broader than just leading fitness classes.
• Question 6: Group fitness classes often follow a specific format or routine (e.g., warm - up, main workout, cool - down). Progressive difficulty levels are more common in individualized training. Customizable workouts for each participant are hard to implement in a group. Focusing on a single exercise type is not typical as classes aim for overall fitness.

Answer:

1. Endurance Training
2. A certified fitness professional
3. A specific format or routine
